Double-Clickable Applications (DCA),
Self-installing Squeak Release (SSR),
Browser Plugin VM (BPV)
We have bundles these three projects together because the skill set required is pretty similar, and because the second will probably be an example of the first. Each of these has a significant platform-specific component to it.

[Feb 27 00, ACG] I posted a "solution" to the corrupted sources issue on various platforms. Using Andreas' excellent plugin implementation of the Zip family compression algorithms, I modified the system startup code as follows:

before opening .changes and .sources files, search the default directory for files with a ".si" suffix.

if there are any .si files, determine which do not have corresponding (presumably expanded) files with the same name, but without the ".si" suffix.

if there are any .si files without corresponding expansions, then, presuming the .si files are GZip compressed files, expand them into files, without the .si suffix.

then, and only then, attempt to open the .sources and .changes files

I was preparing a far more elaborate installation program, but it occurred to me that this might be the simplest possible thing that could possibly work. I posted changesets to the listserv.
